Descripción
The AEA RPQ3 preamp and EQ utilizes our newest 3rd generation circuit design. Two channels of high-output, high-impedance, and low-noise gain with our unique EQ architecture optimizes the performance of your microphones.
OVERVIEW
- Two channels with 85dB of sweet, quiet, and mouthwatering JFET gain
- High-frequency CurveShaper™ EQ and low frequency proximity control
- 68k ohm high-impedance circuitry providing better overall transients, frequency response, and higher output sensitivity
- Post-Mic and Pre-EQ Inserts for convenient routing options
- Switchable phantom-power and polarity invert
- Made in the U.S.A.
ENHANCE YOUR RIBBONS
The AEA RPQ3 Ribbon Preamp and EQ provide two channels of high-output, high-impedance, and low-noise gain with a rich and natural sound that brings out the full potential of your microphones.
Specifically designed for ribbon microphones, the RPQ3 excels at drawing out the warmth and lush sound that ribbons are uniquely known for.
A GAIN POWERHOUSE
The RPQ3 is the tool of choice for all microphones whenever a true and pristine signal path is desired. Our 3rd generation circuitry is the cleanest and most musical design we’ve done yet.
With the RPQ3, you will never consider a source too quiet to record with a ribbon mic ever again. Passive ribbons with low output levels require preamps that supply a high level of output. If the preamp you use doesn’t have enough clean gain, the mic signal may seem too soft or noisy which may be apparent when recording quiet acoustic guitars or strings, especially at a distance or with long cable runs. The RPQ3 eliminates this concern.
